<DIV><FONT face=Arial size=2>There is a formula for calculating =
centerpin size
it is as follows Mic reading - 10 /2 = pin size ( .053 - 10/2= =
21.5)</FONT></DIV>
<DIV><FONT face=Arial size=2>I usually will go up to size 22 =
before
replacing bushings, it is just a preference. Once you have to start =
reaming the
birdeye, it is just as much work as replacing a few bushings. If the =
birdseye
gets too big, it requires sizing if you ever decide that you would like =
to
rebush and go back to a smaller pin. - Chris</FONT></DIV>

<DIV><FONT face=Arial size=2>Hi all,</FONT></DIV>
<DIV><FONT face=Arial size=2>In measuring center pins I have =
discovered that
my pins do not always increase in increments of .001 =
</FONT></DIV>
<DIV><FONT face=Arial size=2>They go #18 is .046</FONT><FONT =
face=Arial
size=2>#18.5 is .047 #19 is
.048 19.5 is 49 #20 is =
50 # 20.5 is 51 # 21 =
is
52 #21.5 is 53 # 22 is
54.</FONT></DIV>
<DIV><FONT face=Arial size=2>I do not have any =
22.5 pins but
presume that they are .055 becuase #23's are .056 and no #23.5 pins =
and wonder
the size for the #24 pins are.059 No #24.5 and then #25 is .063 and no =
#25.5
and the last pin size 26 is .066</FONT></DIV>
<DIV><FONT face=Arial size=2>The break in size progression seems =
to
be between size #23.5 and size #24</FONT></DIV>
<DIV><FONT face=Arial size=2>Question 1. are my missing center pin =
sizes
available? #22.5, 23.5 and 24.5?</FONT></DIV>
<DIV><FONT face=Arial
=
size=2> &nbs=
p;
2. are these larger sizes used by many? {#22 and larger}</FONT></DIV>
<DIV><FONT face=Arial =
size=2>
3.At what size do you =
deide
to rebush rather than repin?</FONT></DIV>
<DIV><FONT face=Arial
=
size=2> &nbs=
p;
4. If larger accurate reamers were available would you think of using =
a larger
pin size?</FONT></DIV>
